Payroll Net Pay with Pointers

Moonshine2183 (26)
Alright, after what seems like forever I'm on the last stage of modifying my Payroll Program. This time I have to sort using pointers and I only have to sort the Net Pay category.

Using one of my earlier programs I've removed content from it until it's in a state where it runs but contains no sorting functions.
____________________________________________________________________________
So now I've to a working program that lacks any kind of sorting and looks like this.

_____________________________________________________________________________
My hints for how to add pointers to the program are...

int *np,tmp;

for (i=0,i<n; i++) np=&netpay[i]; //associating the netpay to np;

temp=np[i];//storing the pointer to a temp
_____________________________________________________________________________
I've been fooling around trying to sort the Net Pay by pointers using these hints for a bit now and I'm still not getting it. Can someone help me out with this silly Payroll program one last time please?

Edit: Please if anyone can help I'd really appreciate it. I've continued to work on this throughout the day and I'm still getting nowhere.

I've been working on this most the day so far and I've experimented with what I think is a simple example program that may be taking me in the right direction.

I'm still trying to work out a way to sort my net pay with pointers in my payroll program though. I could really use some help if anyone is willing.

So I'm still working on this and though I haven't gotten it to work I thought I'd present what I've done if for no other reason then to prove that I'm trying.

Here's what I've got now.

If anyone could take a look at it for me and give me advice about what I'm doing wrong it would be great. I think I am slowly working though it but I'm still stumped at the moment.
